Georadar

Georadar is a simple nondestructive inspection technique of the subsoil. It is a mobile device that consists of a transmitting-receiving antenna connected to a computer. When it moves on a surface the antenna emits electromagnetic impulses and when it finds a material with different electromagnetic properties, the wave is reflected and picked up by the receiving antenna. From the waves emitted and received the software of the team generates images called "radargrams". The measurement of the time elapsed between the emission of the waves and the reception of their reflection allows determining the position and depth of the element to be analyzed. Depending on the frequency of emission used, we will have more or less depth in the exploration. The prospection depth ranges between 20 cm and 30 m, depending on the type of antenna. The management of georadar and the interpretation of radargrams should be carried out by expert operators, usually geologists specialized in this technique. Some of the multiple applications in which you can use georadar are: - Determination of thicknesses in pavements, screeds, slabs ... - Subsurface states below concrete slabs already executed. - Determine the position of reinforcements in concrete structural elements. - The internal state of concrete in beams, pillars, slabs ... - Detection of problems in foundations. - Land studies. - Location of archaeological remains. - Location of cavities. - Location of facilities, pipes, galleries, wells etc ... - Etc….
